Abstract
BROCA é descrita uma broca que compreende uma haste que define um eixo longitudinal. Três nervuras estendem-se em uma curva em torno do eixo longitudinal. As nervuras incluem bordas laterais que estendem-se por uma primeira parte em um primeiro ângulo em relação ao eixo longitudinal e por uma segunda parte em um segundo ângulo em relação ao eixo longitudinal. Um parafuso de avanço estende-se ao longo do eixo longitudinal e tem filetes que estendem-se em um ângulo de rosca. Uma aresta de corte é formada ao longo de cada uma das nervuras. A aresta de corte tem um ângulo de chanfro, onde o ângulo de rosca é menor que o ângulo de chanfro.
